* USB device controllers have lots of quirks. Use these macros in
|
|
* gadget drivers or other code that needs to deal with them, and which
|
|
* autoconfigures instead of using early binding to the hardware.
|
|
*
|
|
* This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
|
|
* some config file that gets updated as new hardware is supported.
|
|
* (And avoiding all runtime comparisons in typical one-choice configs!)
|
|
*
|
|
* NOTE: some of these controller drivers may not be available yet.
